In the case of loader differential, sometimes a mechanism for limiting the differential is installed at the same time. In order to place the mechanism into the housing, a two-piece housing that can be divided into more than two parts is sometimes used. In the two-piece housing, after the components are placed in the housing, install the cover, and fasten the ring gear to the housing after fastening them to each other or both.
? generally speaking, the differential case is cast with malleable cast iron or forged with alloy steel. The main faults in use are: (1) wear of half shaft gear bore and thrust end face; The seating surface matched with the spherical seating surface of planetary bevel gear is worn; The housing hole for installing the spider is worn; The bearing mating surface is worn and the left and right differential housings are cracked.
?? when the fitting clearance of the shell hole matched with the half shaft gear is greater than 0.25mm due to wear, it can be repaired by the sleeve method. The wall thickness of the sleeve can be 2,0-2.5mm. After repair, check the coaxiality of the mounting holes of the left and right half shaft gears. When the end face in contact with the half shaft gear and planetary bevel gear is worn and the axial movement increases, it can be repaired by replacing the thickened thrust pad.
